| Description: |
hsa_circ_0000073 is up-regulated in osteosarcoma cell lines and promotes malignant behaviors (proliferation, migration, invasion, cell-cycle progression) and tumorigenesis. Mechanistically, it functions as a ceRNA by sponging miR-1252-5p to regulate CCNE2 and MDM2 expression, supported by luciferase, RIP, and rescue experiments. |
